Irregular Past Participles in French

In Brief

To form the passé composé, French normally combines a form of avoir or être with a past participle: j'ai fait, elle a pris, nous avons vu. Regular participles follow patterns such as parler → parlé, but frequent verbs often have forms that must be learned individually: faire → fait, avoir → eu, prendre → pris.

Overview

A past participle is a verb form used with a helping verb to build a compound tense. In English, forms such as “done,” “seen,” and “written” play this role. French uses the same basic idea: ai is the helping verb in j'ai écrit, while écrit is the past participle. The complete phrase means “I wrote” or “I have written,” depending on context.

Irregular past participles matter early because many of the least predictable forms belong to the most common French verbs. At A2, the practical goal is to recognize and use a core group confidently in the passé composé. You do not need to infer a hidden rule for every form: learn the infinitive (the dictionary form of a verb) and its participle together.

English can both help and mislead. English also has irregular pairs such as “write/written” and “see/seen,” but French does not divide its meaning neatly between “I did” and “I have done.” J'ai fait can translate either one. Choose the French tense according to the French context, not according to whether the English translation uses “did” or “have done.”

How It Works

The basic construction

The beginner pattern is:

subject + present tense of avoir or être + past participle

Most verbs—including all ten core verbs in this article when used in their ordinary meanings—form the passé composé with avoir:

• J'ai lu le message. — I read the message.
• Nous avons bu un café. — We drank a coffee.
• Elle a mis son manteau. — She put on her coat.

The verb être itself also takes avoir: il a été malade means “he was ill.” Do not confuse the auxiliary a with the participle été.

Ten essential forms

Infinitive	Meaning	Past participle	Example
faire	to do, to make	fait	j'ai fait
être	to be	été	tu as été
avoir	to have	eu	elle a eu
prendre	to take	pris	nous avons pris
mettre	to put	mis	vous avez mis
voir	to see	vu	ils ont vu
dire	to say, to tell	dit	on a dit
écrire	to write	écrit	j'ai écrit
lire	to read	lu	tu as lu
boire	to drink	bu	elle a bu

Accent marks are part of the spelling. In particular, été has two acute accents. The short forms eu, lu, vu, and bu end in u; they do not take an accent.

Useful families

Some irregular forms become easier when learned as families:

• Verbs built on prendre usually keep -pris: apprendre → appris, comprendre → compris.
• Verbs built on mettre usually keep -mis: permettre → permis, promettre → promis.
• écrire → écrit is echoed in décrire → décrit and inscrire → inscrit.
• dire → dit helps with redire → redit, although not every verb ending in the same letters necessarily follows one simple rule.

These families are memory aids, not a license to guess every unfamiliar participle. Check a dictionary when the form is new.

Negatives and questions

In a negative sentence, ne ... pas surrounds the conjugated auxiliary, not the participle:

• Je n'ai pas vu Paul. — I did not see Paul.
• Elle n'a rien dit. — She said nothing.

In everyday questions, the auxiliary still carries the tense:

• Tu as lu ce livre ? — Have you read this book?
• Est-ce qu'il a pris le train ? — Did he take the train?

Object pronouns normally come before the auxiliary: Je l'ai vu (“I saw it/him”). This position becomes important for advanced agreement, discussed below.

Examples in Context

Nous avons pris le train de huit heures.	We took the eight o'clock train.	prendre → pris
Vous avez mis les clés sur la table.	You put the keys on the table.	mettre → mis
Ils ont vu le film hier soir.	They saw the film last night.	voir → vu
Il a dit la vérité à ses parents.	He told his parents the truth.	dire → dit
J'ai écrit un message à Léa.	I wrote a message to Léa.	écrire → écrit
Tu as lu les instructions ?	Did you read the instructions?	lire → lu

Elle a permis aux enfants de sortir.	She allowed the children to go out.	Related family: permettre → permis
Qu'est-ce que vous avez écrit ?	What did you write?	Question with the auxiliary before the participle
Ce matin, il a été en retard et il a eu un problème.	This morning, he was late and had a problem.	Two easily confused participles

Common Mistakes

Using an infinitive after the auxiliary

• Wrong: J'ai faire mes devoirs.
• Right: J'ai fait mes devoirs.
• Why: After the conjugated auxiliary ai, use the past participle fait, not the infinitive faire.

Applying a regular ending to an irregular verb

• Wrong: Nous avons prendu le métro.
• Right: Nous avons pris le métro.
• Why: Prendre does not form its participle by adding -u. Its form is pris and must be learned.

Confusing été and eu

• Wrong: Elle a eu malade hier.
• Right: Elle a été malade hier.
• Why: été is the participle of être (“to be”); eu is the participle of avoir (“to have”). Compare elle a été malade with elle a eu de la fièvre.

Conjugating the participle for the subject

• Wrong: Nous avons prissons le train.
• Right: Nous avons pris le train.
• Why: The auxiliary changes with the subject—ai, as, a, avons, avez, ont—but the participle remains pris. It is not a present-tense verb form.

Putting the negative around the participle

• Wrong: Je ne ai vu pas le message.
• Right: Je n'ai pas vu le message.
• Why: Ne and pas surround the conjugated auxiliary: n'ai pas. The participle follows.

Translating English tense forms word for word

• Wrong approach: Assuming j'ai vu can only mean “I have seen.”
• Better reading: J'ai vu Marie hier means “I saw Marie yesterday.”
• Why: The French passé composé commonly describes a completed past event where English uses the simple past.

Usage Notes

These participles are not rare or literary. They occur constantly in conversation, messages, news, and everyday storytelling. Several also belong to fixed expressions: j'ai eu peur (“I was scared”), j'ai eu raison (“I was right”), ça m'a fait plaisir (“that made me happy”), and on a pris un café (“we had a coffee”). Learn the whole expression when the English verb is different.

French spelling does not always reveal pronunciation. fait and faits are normally pronounced alike, as are pris/prise only partly alike: the final consonant is heard in feminine prise. Listening practice therefore needs to be paired with spelling practice.

In informal speech, on a often replaces nous avons: On a vu Julie is a very natural way to say “We saw Julie.” This changes the auxiliary form, but not the participle.

Beyond the Basics / Advanced Use

You do not need to master all agreement rules at A2, but you will encounter them later. With avoir, the participle usually stays unchanged when the direct object (the person or thing directly affected by the action) follows the verb:

• Elle a écrit les lettres.
• Ils ont pris les photos.

In standard written French, it agrees when that direct object comes before the participle:

• Les lettres qu'elle a écrites — the letters that she wrote
• Les photos qu'ils ont prises — the photos that they took
• Je les ai vues. — I saw them (where les refers to feminine plural things or people)

The added endings mark gender and number: écrit, écrite, écrits, écrites. With many forms, the spelling changes even when pronunciation does not. This is an advanced rule, so first make the base participles automatic.

A past participle can also work like an adjective—a describing word—or appear in the passive voice, where the subject receives the action. It then agrees with the noun it describes:

• une décision prise rapidement — a decision made quickly
• des instructions écrites — written instructions
• La porte est mise sous surveillance. — The door is placed under surveillance.

Finally, these forms are not limited to the passé composé. Compound tenses reuse the same participle with a different auxiliary tense: j'avais vu (“I had seen”), elle aura écrit (“she will have written”), and après avoir lu (“after reading”). Once vu, écrit, and lu are learned, that knowledge carries into several later structures.

Practice Tips

1. Learn in three-part chunks. Say and write faire — fait — j'ai fait, prendre — pris — j'ai pris. The example prevents the participle from becoming an isolated vocabulary item.
2. Sort the forms by sound or family. Make one group for eu, vu, lu, bu, another for pris, mis, and another for fait, dit, écrit. Then test yourself in both directions: infinitive to participle and participle to infinitive.
3. Retell one day in ten sentences. Use prompts such as “What did I do, see, read, write, eat, or drink?” Add one negative and one question so that you also practise word order: Je n'ai rien vu. Tu as lu mon message ?
